Contract Development Toolkit based on EOSIO.CDT

Version : 1.6.3

CyberWay.CDT is a toolchain for WebAssembly (WASM) and set of tools to facilitate contract writing for the CyberWay platform. In addition to being a general purpose WebAssembly toolchain, CyberWay specific optimizations are available to support building CyberWay smart contracts. This toolchain is built around Clang 7, which means that CyberWay.CDT has the most currently available optimizations and analyses from LLVM, but as the WASM target is still considered experimental, some optimizations are not available or incomplete.

If you have previously installed CyberWay.CDT, run the uninstall script (it is in the directory where you cloned cyberway.cdt) before downloading and using the binary releases.
